Using blockstream green wallet on Android. In the app, I have an on-chain wallet and a lightning. The thing is, I noted the lightning wallet has its own seed-phrase (12 words not sure if they are BIP 39).
But Blockstream does not seem to support Bolt12 offer, which I need to redeem payout from Ocean mining pool. I also read some posts saying Phoenix is a great wallet which offers (pun intended) it.
So I am wondering how trustworthy and transparent is that compared to Blockstream. Are there pros and cons that I should be aware of? I also read somewhere that Phoenix runs a light node on my phone. I am not absolutely sure if it is true, but seems like a big burden for a mobile device? Does it mean huge drain on the battery and I have to stay continuously online to keep the channel alive?
